Of the total, 25% of land area is highly degraded, 8% moderately or slightly degraded, 36% stable and 10% improving (FAO-State of the World's Land and Water Resources for Food and Agriculture. Soil erosion also leads to lower crop productivity because of loss of water, organic matter and soil nutrients.

A 50% reduction in soil organic matter has been found to reduce corn yields by 25%. for soil erosion affecting a single area of more than 1 hectare for poaching on a stretch of land (at least 2m wide and 20m long) next to an inland freshwater or coastal water.
